If your old Dico Model 10 or Dexter DX12.5 actuator has seen better days, this unit drops right in as a perfect fit. The Dexter Zinc-Plated Brake Actuator bolts onto a standard 3" wide channel tongue and uses a 2-5/16" ball, so there’s no guesswork or modification. Rated for 12,500 lbs with a 1,250-lb maximum tongue weight, it easily handles heavy-duty applications like multi-axle boat or utility trailers. It’s built strong and installs using the same bolt pattern, so the swap is quick and straightforward.
The unique roller setup inside this actuator reduces resistance as it telescopes, which keeps the motion straight and consistent. That smoother engagement means your drum brakes come on evenly—no jerking, no sudden grab. Whether you’re easing down a ramp or slowing on the highway, the hydraulic system syncs up naturally with your tow vehicle’s brakes to deliver steady stopping power every time.
Durability is where this actuator really shines. It’s made from sturdy steel that resists bending even in tight jackknife conditions, and the zinc-plated finish fights corrosion from water and road salt. That plating makes it ideal for trailers that live near the coast or spend time around wet launch ramps. The breakaway kit is built in too, providing an added layer of safety if your trailer ever disconnects unexpectedly.
This model is made specifically for hydraulic drum brakes and does not include a reverse lockout. It’s best paired with free-backing brake assemblies so you can back up without engaging the brakes. If you ever decide to add an electric lockout later on, it’s easy to convert using the matching solenoid valve designed for this Model 10 actuator series.

It has remained durable during salt water use. No problems at all.

This coupler is trash. I would replace it if I could afford a different one.

If it is the latch spring that broke, then I am sorry as I do not have a latch repair kit to offer.
